Well all of that is extra biblical. The bible says that they were tribes in Caanan, and they were obviously not superhuman as the Israelites drove them out, along with the other wicked people living in those lands. If the flood wiped out all of the human race, except 8 people, then they were descendents of Noah. Giants are still among us, and it is now known to be caused by hormonal problems or genetics.
"Giants" or men of renown happen along in history, George Washington was a "giant", but so was Hitler. They can be extremely wicked men, which was the crime that God had against them.
Again, Joshua was "a fallen one". The term clearly does not always mean a wicked fallen angel.
Well all of that is extra biblical.Bullinger is rolling in his grave with you saying that. ; ) He was kind of a stickler about such things.
Thanks for the discourse...very interesting subject.
